Input Mirror (IM) Alignment Restoration

After the HAM2/3 were brought back went about restoring input pointing alignment since whenever these HAM ISIs trip, the IM mirrors get shifted.  Cheryl has a procedure for checking/restoring this alignment here.

So from about 9:30 to about 11:30am PST addressed input mirror alignment.

Made changes to several optics.  One oddity was the IM3 Pitch.  It's slider has a limits of +/-25,000, but the value is ~ 57,000 (and only way to move more positive is to enter a value by hand.)  After restoring optics, checked that we were in the ball park by looking at IM4 Trans QPD (and we looked fairly close).

Attached is a trend of last 24hrs (with earthquake at ~9:00utc.
